Population justification: The global population size has not been quantified, but the species is described as locally common in Ethiopia and more scarce elsewhere (del Hoyo et al. 2006).

Trend justification: The population is suspected to be in decline owing to ongoing habitat destruction and fragmentation (del Hoyo et al. 2006).
